My invention relates to a new and useful improvement in an elect-ric heating device intended for use both as an electric plate and especially adapted for use when used as a Water heater for shaving purposes. i

It is an object of the present invention to provide a device of this class which will be simple in structure, economical of manufacture, durable and highly efficient in use.

Another object of the invention is the provision of an electric heating device `of this class in which a container may be easily and quickly removed from the' heating element` toprovide an electric heating plate.

Another object of the invention is the provision of a simple and effective means of mounting the heating element in its support so that it may be easily and quickly removed therefrom and placed therein.

' Other objects will appear hereinafter.

The invention consists in the combination and arrangement vof parts hereinafter cle-- scribed and claimed.

The invention will be best understood by a reference to the accompanying drawing f which form` a part of this specification and in which,

Fig. 1 is a central vertical sectional view of the invention.

Fig. 2 is a sectional view taken online 2 2 of Fig. 1 with Vparts broken away. y

Fig. 3 is a sectional view taken on line 3 8 of Fig. 1. v

In the device there is provided a container comprising a cylindrical member 7 having a base 8 mounted therein intermediate the ends of the cylindrical member to provide a container, the side walls of which project down wardly beyond the base 8. The cylindrical 7 supporting base 9 is provided at its lower end with an outwardly flared edge 10 pro- Y against which engages a plate 12 carrying supporting legs 11. A

disc 154 made from insulating material is positioned in the base 9 so as to engage at its portion of the bead 15 `which is pressed inwardly of the base 9 intermediate the ends thereof. Embracing the upper portion Yof the insulating disc 14 is a 1928. Serial No. 280,533.

upper surface of a cover 18 formed from mica Il or othersuitable insulating. material which serves to cover grooves or recesses' 19 formed in the upper face of the insulating disc 14 and in which is positioned the heating element 2O.` A bolt 22 is hub 2,1 and through the plate 12, the nut 22 serving to clamp the plate 12 against the shoulder 13 to clamp, through the cooperation of the bolt 22, the insulating disc 14 against the bead 15, While at the ring 16 in position. The wires 23 are projectedtlirough the base 9, a suitable in-v` sulating sleeve 23 being provided for this purpose, the wires being connected to the terminals 24 and 25.

Mounted on one side of the container or cylindrical member 7 is ahandle 26.

Mounted on the inner surface of the container 7 and extending axially thereof, are the angle irons 27 and 28 which serve as guides 7 or an auxiliary container positioned in the member 7. This auxiliary container comprises the arcuate wall 29 and the wall 30. Tongues 31 are punched inwardly adjacent the lower end of thel wall 29 and a tongue 5 32 is punched inwardly adjacent the lower end of the wall 30, these tongues serving to engage and support a bottom 33 which is positioned above the lower endsof the por- 33 spaced above the base 8 as clearly appears in Fig. 1. n

The construction is such that when water or other liquid is poured into the container a container for water which may be heated A cover 35 is mounted on the containment 20.

to any desired degree by the heatingl elema projected through the 0 the same time, retaining tions 29 and 30, so as to retain the bottom a 1t has access to the space below the bottom 'x90 By lifting the cylindrical member 7 from about the rlng 16 an electric heating plate is provided which may be used for any desired purposes. f U

" There is thus provided in the single device a water container which may befelectrically, heated and a heating plate which may be used for ordinary purposes when the water container is removed therefrom. lo The device, as shown, is one which may be compactly built and transported from, place to place without requiring very much space.

While I have illustrated and described the preferred form of my invention, I do not wish to limit myself to the precise details of structure shown, but Adesire to avail myself of such variations and modifications as come within the scope of the appended claim.

Having thus described my invention what K ,9 I claim as new and desire to secure by Ilet- -cters Patent is: I

A device of the class described, com rising; a cylindrical member having a ead pressed inwardly intermediate its ends and ,5 flared outwardly adjacent one end to provide a vshoulder on its inner side; a ring mounted within said member; an electric heating plate engageable by said ring and engaging at its undersurface the uppper side of said bead; a closure plate positioned within the end limits of said member and engaging said shoulder; and a bolt projected through said heating plate and said closure plate for clamping said heating plate against said bead and said closure plate against said shoulder.

In testimony whereof I have signed the foregoing specification. I
